Users to register only lower case letters
Hi, I have this register page , and i would like to have the script register only lower case letters : pretty
I do not want it to register :Pretty , PRETTy , PRETTY ...
Here is the code , what do i need to add to it ?
public f开发者_StackOverflow中文版unction addField($field_name){
if (!array_key_exists($field_name, $this->fields))
{
if ($field_name=='username') {
$field = new field_join_username();
parent::registerField($field);
}
if ($field_name=='email') {
$field = new field_join_email();
parent::registerField($field);
}
}
parent::addField($field_name);
}
Where's that code taken from? Are you trying to change existing code?
As far as I can see, this only adds fields not values of fields where the strtolower
should be applied, so applying strtolower to field_name won't do the trick ... but it's hard to guess where to place strtolower without seeing the correct code snippet.
